Abstract
A draining device for removing processing water attached to a lens includes: a first lens holding shaft to which a cup attached to a refractive surface of the lens as a processing jig can be fitted; and a rotating unit which rotates the first lens holding shaft to remove the water by centrifugal force.
Claims4
A lens processing system comprising:
- a lens processing device which processes a lens while spraying processing water on the lens;
- and
- a draining device which rotates the processed lens to remove the processing water attached to the processed lens by centrifugal force;
- wherein the lens processing device comprises a first lens holding part to which a cup attached to the lens can be fitted and a lens processing member which processes the lens held by the first lens holding part;
- and
- wherein the draining device comprises a second lens holding part to which the cup attached to the lens can be fitted and a rotating unit which rotates the second lens holding part.
